At least it wasn't a bare boob.^
I have bats, too. I wish more of them would flock near my house, to eat up all the horrid mosquitos.

I did build and hang a bat box for a long time, but they never went near it. They've come inside a few times; once on my birthday. It was funny: swoop, swoop, swoop; window. The dogs were completely flummoxed.

Dogs and nature abhor a vacuum.
